A.Hauck M.J.Moll a D.G.Dutcher ATTORNEYS United States Patent R 3,022,881 AUTOMATIC CONVERSION IlVIMERSlNG MACHINE Willard 3'. Harper, Middletown, Paul A. Hauck, Union, and Martvig J. Moll and Donald G. Dutcher, Fair Haven, N.J., assignors to Hanson-Van Winkle-Munning Co., Matawan, N.J., a corporation of New Jersey Filed Dec. 29, 1958, Scr. No. 783,591 31 Claims. (Cl. 198-49) The present invention relates to Automatic Conversion Coating Machine and has for an object to provide a mechanism designed to function specifically with one work load that performs a wide range of operational requirements, namely:

Any treatment cycle, where metal parts or any materials require a sequence of different processing baths to prepare the work for a specific purpose, such as cleaning to remove dirt, grease, etc., paint preparation, oxide or phosphate coatings, blackening of metal surfaces, pickling of work surfaces, plating, anodizing, dye or dip treatments, where the treatment in each bath is individually controlled and the entire mechanism fully automatic.

Another object of the invention is to provide a mechanism where the treatment timing in each bath may be set or varied without disturbing the functional operation of other set treatments in the process cycle, where these variables can be preset differently for each new batch to compensate for processing characteristics of each new batch, where the work load can skip a specific vat or a series of vats by an intelligence that cycles and controls this single functional load of the machine, where this intelligence can be made to repeat several operations in a back and forth shuttle arrangement before proceeding to other required treatments for a specific process requirement, where this one load can be received at one end, discharged at the other end by automatic methods, or designed to shuttle the load back at a high speed todischarge at the same end as loading, and where the load may be a rotating barrel, basket, tray, tipping work crate, a rack of work or a single large piece. A further object of the invention is to provide a machine wherein the rotating work carrier, where it is a barrel, cylinder or other form of receptacle may be varied in speed to suit each specific treatment tank, reverse rotation, stop, start rotation, all at the will of a control intelligence designed to provide the variables necessary for different processing baths, i.e.

(A) Cleaning for removal of dirt at high revolutions per minute.

(B) Deburring, where different speeds are required, de pending on specific baths, deburring compounds, shapes and conditions of parts, solutions, density and composition.

(C) Salt bath treatments with subsequent cleaning cycle, drying, etc.

(D) Fluxing and galvanizing where a work load may turn, pass through a top blanket in the kettle and operations peculiar to hot galvanizing, tinning, etc., where a control intelligence can perform many functions on the one operating work load of the machine.

(E) Very slow speeds to prepare a soft conversion coating on the metal parts or materials, where the higher speeds in prior treatments would rub off the coating as rapidly as applied, i.e., blackening, phosphating, blueing of metal surfaces, etc.

A still further object of the invention is to provide a 3,022,881 Patented Feb. 27, 1962 mechanism for the metering of a defined work load, either in quantity, volume or weight, an automatic means of dumping or transferring the work load to a cylinder or container where a cover is used to prevent spillage during processing, an automatic device to close and lock the cover, subsequent cycle processing in any of .the methods indicated previously in the immediately preceding paragraph, and an automatic device to open the cover at the opposite end of the cycle to spill or discharge the load to a receptacle, belt, hopper or other receiving bucket or conveyor device, where the load then receives other manufacturing or assembling operations, all such sequences being performed automatically with this single work load machine.

The invention has for a further purpose to produce an automatic conversion coating machine having unique features bringing important advantages in process flexibility, work adaptability and labor savings.

For purposes of illustration the invention is shown in a straight-line machine having a loading station at one end and an unloading station at the other end and with a barrel type receptacle for processing small parts like spark plugs, nuts, screws, pins, etc.

With the foregoing and other objects in view, the invention will be more fully described hereinafter, and will be more particularly pointed out in the claims appended hereto.

In the drawings, wherein like symbols refer to like or corresponding parts throughout the several views.

FIGURE 1 is a side elevational view with parts of the main framework and tanks or vats broken away and shown in section and with the elevator and barrel receptacle carried thereby shown in full lines in elevated position and in dotted lines in lowered position, all of a form of machine constructed in accordance with the present invention.

FIGURE 2 is a side elevational view of the machine with the elevator in elevated position and the barrel receptacle at the Load Station.

FIGURE 3 is a top plan view of the machine with the barrel receptacle at the Load Station and in dotted positions at an intermediate tank station and at the Unload Station.

FIGURE 4 is an end elevational view of the machine taken from the right-hand end of FIGURE 1.

FIGURE 5 is a vertical transverse sectional view taken on the line 5-5 of FIGURE 1.

FIGURE 6 is an isometric view of the machine taken from the Load Station with the cover of the barrel receptacle open to receive a load.

FIGURE 6A is a fragmentary isometric view taken on an enlarged scale of a portion of the barrel receptacle and cover showing a form of yieldable detent for holding the cover in open or closed positions.

FIGURE 7 is also an isometric View being a blow-up of the Load Station end of the machine similar to FIG- URE 6 but with parts greatly magnified for clarification.

FIGURE 8 is a vertical transverse sectional view taken on the line 88 in FIGURE 9 through the work carrier carriage on an enlarged scale.

FIGURE 9 is an end elevational view taken on a smaller scale looking from the left of FIGURE 8 at the drive end of the barrel receptacle.

FIGURE 10 is an edge elevational view of a form of trip device and limit switch which may be used at the Load Station and showing a fragment of one of the paddle arms engaging the stop member.
